From: Kalpak Shah Subject: [PATCH] Add i_version_hi for 64-bit version Date: Sun, 18 Mar 2007 15:43:39 +0530 Message-ID: <1174212819.3282.10.camel@garfield> Mime-Version: 1.0 Content-Type: text/plain Content-Transfer-Encoding: 7bit Cc: Andreas Dilger , TheodoreTso , Dave Kleikamp , Eric Sandeen To: linux-ext4 Return-path: Received: from mail.clusterfs.com ([206.168.112.78]:38011 "EHLO mail.clusterfs.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1753316AbXCRKMv (ORCPT ); Sun, 18 Mar 2007 06:12:51 -0400 Sender: linux-ext4-owner@vger.kernel.org List-Id: linux-ext4.vger.kernel.org Hi, This patch adds a 32-bit i_version_hi field to ext4_inode, which can be used for 64-bit inode versions. This field will store the higher 32 bits of the version, while Jean Noel's patch has added support to store the lower 32-bits in osd1.linux1.l_i_version.
